3 Claims. (01. 4-199) My present invention relates to waste and overflow outlets for baths, sinks, basins and the like, and more particularly to a unitary fitting for such waste and overflowoutlets.

My present invention is adapted for use in connection with any receptacle for liquids in which it is desired to provide an outlet for discharging the liquid therefrom, and which will function to prevent the overflowing of the receptacle, and

10 prevent the level of the liquid in such receptacle from rising above a predetermined height. Also, my invention is adapted as a unit to be attachable to, or detachable from such receptacle, and the fittings to be used in conjunction with the waste 15 and overflow outlets may be readily assembled and disassembled. while the waste and overflow outlet is in situ with respect to the receptacle.

A feature of my invention is an improved waste and overflow outlet fitting for a receptacle for 20 liquids, such as a bath tub.

A further feature of my invention is an improved waste and overflow outlet fitting for a re-' ceptacle such as a bath tub, and in which is housed the operating mechanism for a waste and 25 overflow valve mechanism.

Otherfeatures of my device will appear as the description of the invention progresses.

In the accompanying drawings: Fig. 1 is a sectional'side elevation of the waste an outlet end of a receptacla'such as a bath tub,

and to which my present invention has been attached, the structure embodying the invention being shown in sectional elevation, and with the waste valve in closed position; 35 Fig. 2 is a sectional elevation through the waste outlet showing the waste valve in open position; Fig. 3 is a front elevation of either Fig. 2, or the corresponding portion of Fig. 1, with the strainer plate broken away to show the outlet 4 valve operating mechanism, and with a portion of the outlet valve also being broken away, and

Fig. 4 is a sectional plan view taken on the line 4-4 of Fig. l, and looking in the direction of the arrows.

45 Referring to the drawings, [0 designates a re ceptacle, such as a bath tub or other receptacle ill for liquids such as water. The waste outlet end of the receptacle II] is provided with a waste outlet opening I l and an overflow outlet opening 50 12, arranged at the bottom of'and adjacent to the top, respectively, of the bath tub I0.

In my present invention I attach to the bath tub in a waste and overflow outlet fitting, and

attach the same in such a manner as to register 65 withthe waste outlet II and overflow outlet 12.

The waste and overflow outlet fitting is designated by the reference numeral l3, and may be of any suitable'material, butpreferably a casting, such as a casting of brass, copper orthe like. 'The waste and overflow outlet fitting l3 5 in the present instance is provided with a lateral outlet Ma and thus is particularly adapted to be utilized in connection with above the floor plumbing installations. i

The waste and overflow outlet fitting i3 is provided at itsupper end with a threaded opening adapted to receive the external threads of a connecting member M. The member l4 acts as a means for securely clamping the upper end of the waste and overflow outlet fitting I3 to the bath tub Ill. Between the outer surface of the bath tub Ill and the facing of material around the threaded hole in the waste and overflow outlet fitting I3 is placed agasket or washer 15 of preferably flexible resilient material, and this 120 gasket or washer l5 assists in 'maintaining a fluid-tight joint between the upper end of the waste and overflow outlet fitting l3 and the'over flow outlet l3 ofthe bath tub l0.

The connecting member I4 is hollow, as shown 2 in Figure -1, and is provided with internal threads which cooperate with external threads on a combined strainer and bearing member IS. The bearing is designated by the reference numeral l1 and is' positioned with respect to the outer s circumference of the member It by the spaced radially extending spokes l8.

Rotatably mounted in the bearing is a shaft l9, provided with an offset portion .20, and with a shaft portion 2| arranged parallel to the shaft E9. The end of the shaft 19 extends outwardly of the bearing I! to a point within the bath tub ID, and has secured to such end, by nut 22, an operating handle 23, and by meansof which the shaft l9 may be rotated to move the parallelly arranged shaft portion 2| thereof about the shaft I9 as an axis. Pivotally mounted on the'shaft extension 2| is the upper end of an operating connecting rod 24,-such rod being prevented from excessive longitudinal movement on the shaft extension Him the washers 25, and is prevented from accidental removal therefrom by the pin 26. The connecting rod 24 extends downwardly to a point to be hereinafter described. 3

The lower end of the waste and overflow outlet fitting I3 is provided-in addition to the side waste outlet member l4--with an internally threaded opening 21 to receive the external threads on a connecting member 28. The waste outlet H ofthe bath tub in has the material of 5 bers 34, the T become pressed between the frustrum of the cone 29 and the flared portion 3!] of the member 28to thereby establish a fluid-tight joint between the bath tub l and the waste and E3. The gasket 3! has the outer portion thereof folded over the flared portion 30 to be engaged by a member to be hereinafter described.

Fitting into the open flared end of the member 28 is the fitting 32. The outer portion of the fitting 32 is beveled to fit into the open flared mouth of themember 28 and the peripheral edge 33 engages with the folded-over portion of the gasket 3! so that when the member 32'is brought into close association with the member 28 a substantially fluid-tight joint is established therebetween. t

The body of the member 32 is provided'with a plurality of spaced perforations through which extends the cylindrical portion of T-shaped memthereof being formed by the bar -35 extending from and engaging the inner face of the member 28 and a portion of the member 32. The end of each of the T-shaped members 34 is threaded to receive a nut 36 and by means of which the member 32 is firmly clamped in position with respect to the member 28.

Formed in the member 32 is a rectangular passage 31 and at the sides of the longitudinal nassage are formed slideways 38, as clearly shown in Figure 2. The face of the outer peripheral edge of the rectangular passage 31 lies in a plane that lies at an angle to the slides 38 and forms a valve seat for a valve member 40.

Slidably mounted in the slideways 38 is a frame 39 which has secured to or formed integral therewith the valve 40, said valve 40 having its inner face, as viewed in the drawings, adapted to enage with and seat, on, or be removed from the valve seat formed on the outer peripheral edge of the rectangular passage 31. The frame 39 is 'wardly and downwardly, does not provided with a perforation 4! and through which extends an offset member 42 formed integral w and at the lower end of the connecting rod 24.

'" Suitable means, as the washer All and nin M. a

employed to maintain the offset member 42 and frame 39 in operative relation with each other,

The construction just described is such that when the shaft I9 is rotated by the operatin handle 29, the connecting rod 24 is moved unwardly and/or downwardly, and on viewing the structure shown particularly in Figures 1 and it will be apparent that the frame 39 moves wer ti-cally upward and/or downward. The valve i i however, although the same moves vertically unmove vertically either upwardly or downwardly with res ect to thevalve seat formed at the outer peripheral I edge of therectangular opening 31. On referring to Figures 1 and 2 it will be noted that the lower surface of the bottom of the bath tub ill will be in substantial alignment with the lower edge of the rectangular opening 31 and that when the valve 40 is moved from the closed position shown in Fig. l to the opening position shown in Fig. 2

I such valve member will move vertically upward but at an angle to the plane of the valve seat above referred to and will allow a free, clear passage for fluid that may be held within the bath tub l0. This is a particular advantage in clearing the bath tub ill of foreign or solid matter as well as permitting all of the fluid to drain therefrom.

The tubular portion of each of the T-shaped members 34 is drilled and threaded to receive the threaded ends of bolts G6,,and such bolts are utilized for the purpose of clamping a strainer 47 over the valve 40 and over the waste outlet ll. Such a strainer however is easily removed should it be desired to manipulate or adjust the elements forming the waste outlet closure.

The entire structure above described is easily and readily attached to the waste outlet end of the bath tub Ill, and may be removed therefrom at any time with a minimum of effort.

. Whereas I have describedmy invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.

I claim:

1. An improved unitary waste and overflow outlet fitting for receptacles for liquid and the like having waste and overflow openings, comprising, in combination, a hollow body member provided at its endswith waste and overflow openings, connecting mechanism for securing the hollow body to the receptacle with the said openings thereof in alignment with the corresponding openings in the receptacle, a valve seat seat.

2. An improved unitary waste and overflow outlet fitting for receptacles for liquid and the like having waste and overflow openings comprising in combination, a hollow body member provided at its ends with waste and overflow openings adapted to register with. the corresponding openings in the receptacle, means for securing one end of the hollow body member to the receptacle with its opening in alignment with the overflow outlet opening in the receptacle, connecting means for attaching the other end of the hollow body member to the receptacle with its opening in alignment with the waste outlet opening of the receptacle, a conical valve seat structure associated with said connecting means and having a valve seat formed at the outer flared end thereof and lying within the limits of the receptacle, said valve seat lying in a plane at an angle to the vertical, guideways formed in said conical valve seat structure and forming a vertical track on each side of the valve seat structure, a valve associated with said valve seat, means on the valve cooperating with the guideways, whereby the valve is guided perpendicularly of the valve seat and simultaneously guided in a vertical direction, a shaft rotatably mounted in the connecting means at the waste outlet end of the fitting, a lever for rotating said shaft, and a connecting rod extending between said shaft and the valve, for operating said valve, whereby rotation of the shaft causes a reciproeating movement of the valve in a vertical direction with respect to the valve seat structure, and a vertical movement of the valve with respect to the valve seat.

3. The combination with a receptacle provided with an outlet opening, outlet fitting means therefor comprising a hollow member having an opening at one end conforming generally to the contour of the outlet opening of the receptacle, means for water-sealingly attaching said hollow member to the periphery of said outlet opening, a valve seat formed on said hollow means, said valve lying in a plane transverse to the axis of the outlet opening of the receptacle, a movable valve member operatively associated with said hollow member and arranged to be seated upon said valve seat in its closed. position, guideway means associated with said hollow member and with said movable valve member for guiding said movable valve member simultaneously vertically and. perpendicularly from its closed position with said. valve seat to an open position, while maintaining said valve at all times parallel to the valve seat, and means for moving said movable valve member to and from its closed and open positions at will.
